I found this web app the other day that I found useful. I was trying to figure out how I was going to tackle some of my time goals for some local segments near my house, and wondering how much of an impact my weight loss since the fall will help.

Anyway, I thought this was a pretty cool tool. With it, I could easily figure out just how much power and speed I had to put out to make my time goals at my new weight. I wish there was an Android based version too as I don't have an Apple phone.

    Nice find. Probably a little TMI for me. I just want to get & go.

    I spent a while on that website last year, trying to work out what kind of speed i'd be able to attempt M. Ventoux at, given I knew my FTP and had a fair idea of what weight I'd be by maybe june this year... To keep to a sustainable wattage, it was likely to take me nearly 3 hours, at an average of around 7.5kph, and to keep to that cadence i'd have needed to fit the gearing from my MTB... at which point I decided that mountains weren't my natural environment until I lose another 35kg or so...

    Yeah, its definitely oriented to the data geeks I suppose :) Guess I have enough of that in me to like it (hah).

    I can see this as really nice for someone who wants to improve their time on, say, a race or to keep up a certain pace with a riding group, and wondering what would happen if they altered variables in their control (bike weight, body weight, FTP).

    Mark,

    I just looked at my Strava data and saw that I did Ventoux in 2hr 49 mins back in 2012. I was about 105+ Kg then. Avg speed was 7.9 kph and avg estimated power was 196w. It was and still is the toughest climb I've done. I'm quite a bit lighter now and a much stronger climber. I reckon I could do it in under 2:30 now, maybe 2:20 but it is a beast!!

    That pretty much matches up with my figures at the time I calculated it mate, little bit heavier, and sustainable power over that duration was around 205w, but it can all go to batshit as soon as the wind blows, can't it...

    Not half. I climbed Ventoux on 4 separate occasions within a 4 week period and had temp variances from 0C to 38C at the summit. No wind to 80kph gusts after Chalet Renard. It's like a box of chocolates, you don't know what you'll get :)
